The existing traffic infrastructure in agglomerate areas is surcharged in rush hours. This paper discusses some possible solutions of efficient allocation of the scarce good road capacity. It focuses on the economic view. An internalisation of external costs by road pricing would be the first best method. Because it is very complicated to install such a system of internalisation, a second best method is examined: regulatory parking policies. Since there is no existing system of parking policies in this specific area in place, a possible scenario of parking taxes under economic aspects is developed for a defined area in Berlin-Wilmersdorf. We examined the average congestion costs, the opportunity costs of use and the cost of supply per parking space. In addition a representative survey has been conducted to reveal the commuter's willingness to pay, for a free parking space. Finally an analysis of possible economic and infrastructural effects of parking policies on traffic is made.
